Clause Requirement + Test Result - Remark Verdict

8.9.1.2 Valved particle filtering half mask Not such mask N
A total of 12 valved particle filtering half masks N
shall be tested: 3 as received, 3 after
temperature conditioning in accordance with
8.3.2, 3 after the test for simulated wearing in
accordance with 8.3.1and 3 after the flow
conditioning in accordance with 8.3.4.

The particle filtering half mask shall be fitted N
securely in a leaktight manner but without
deformation on the Sheffield dummy head.
The flow rate at which the resistance is measured N
shall be corrected to 23 C and 1 bar absolute.

8.9.2 Exhalation resistance P
Seal the particle filtering half mask on the P
Sheffield dummy head. Measure the
exhalation resistance at the opening for mouth
of the dummy head using the adapter shown in
Figure 6 and a breathing machine adjusted to
25 cycles/min and 2.0 l/stroke or a continous
flow 160 l/min. Use a suitable pressure
transducer.

Measure the exhalation resistance with the Measured 2.0 mbar at 160 P
dummy head successively placed in 5 defined l/min.
positions:
- facing directly ahead P
- facing vertically upwards P

- facing vertically downwards P
- lying on the left side P
- lying on the right side P
8.9.3 Inhalation resistance P

Test the inhalation resistance at 30 l/min and 95 Measured 0.6 mbar at 30 P
l/min continuous flow. l/min, and 2.2 mbar at 95
l/min.
